What to do: Improve air circulation by moving the plant to a spot with better airflow. Remove the heavily affected leaves to stop the spread.
Water Splashing
PossibleHow to tell: Small brown spots appear after watering, usually near the base of the plant.

When to worry
If the spots are spreading quickly or covering most of the foliage, the plant needs immediate treatment. Small, isolated spots are usually manageable with better care.
Stopping it coming back
Ensure good airflow around the plant and keep the foliage dry when watering.
